Pediatric emergency physicians are experienced in the diagnosis and treatment of all types of emergencies in infants, children, teens, and young adults. They usually treat the following types of emergencies:
Solar irradiance. It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Indeed, studies show that solar variability has played a role in past climate changes.
Another unusual aspect of recent climate change is its cause: past climate changes were natural in origin (see FAQ 6.1), whereas most of the warming of the past 50 years is attributable to human activities.
